Awesome you scored some SD heads / Carb / Exhaust Mans for the car !
You will need the special RoundPort head-to-block bolts too.
Some are same as D-Port , and some are different. iirc
The distributor from the 72 is fine enough replacement.
Should be recurved/dialed-in for proper performance tho.
SD was points type, but the housing was larger where it slides into block.
Also had a larger stronger gear on end of distributor due to the high PSI oil pump.
The cam used a smaller mesh/gear pattern for conjuction with larger dist gear.
The block also had a larger hole for the distributor.
Ram IV / 041 cam will be decent choice.
Some of the best Pure Stock racer/builders have said the IV cam is not optimal for low compression roundport 455's. Something in between 744 and 041 grinds is said to have been needed. But PMD didn't make anything in between.
